Requires a Chris King Conversion Kit for installation

Our ThreadFit™ 24 bottom brackets are designed and built to be durable, serviceable, and silent.

Manufactured to create a precise and functional interface between your frames' bottom bracket shell and your 24mm cranks, our ThreadFIt™ 24 bottom brackets ensure that your cranks will spin lightly and without interference. To help with bike fit issues we have developed a range of conversion kits that allow our ThreadFit™ 24 to be used with a wide selection of road and mountain bike cranks.

As with all Chris King components in our ThreadFit™ 24 bottom brackets it all starts with the bearings.

We make our bearings in-house and our process allows us to place more balls per bearing than our competitors.

More rolling elements per bearing translates to a stronger overall bearing system.

A bottom bracket-specific upgrade to our legendary sealing system allows the bearings to be purged and re-greased using our precision made injector tool.

This combination of strength and serviceability gives us the confidence to offer an industry-leading 5-year warranty on our bottom brackets.

Engineered, manufactured and assembled in Portland, Oregon USA. 5-year built-to-last warranty.

Easily serviceable with our integrated grease injection system. Legendary in-house made bearings.

Available ceramic bearing upgrade. Easily inject your choice of grease for different riding conditions.

Available in 8 beautifully anodized colors.

Weights: 89.06grams- Stainless Steel 

             85.02grams- Ceramic.

Angular Contact (A/C) ABEC-5 Bearings and Bottom Bracket

For the ultimate bottom bracket bearings, and for many hubs, these are the best bearings available for speed, balance, and longevity. Because they utilize a large surface area design, the load from all the balls is shared equally at all times, spinning faster than any radial bearing where only 30% of the balls may be taking the load. A patented Enduro Bearings design, they may be serviced just as any other bearing with no special tools needed. Perfect for disc brake wheels where you need to remove all wheel play.  Just remember, the RED color seal side is the loading side; don’t BLACK out! Also now available in ceramic for 2015.

ZERØ Ceramic Bearings and Bottom Bracket

Proven time and again in World Cup race conditions, ZERØ Ceramic bearings are the ultimate race day weapon. Silicone Nitride (Si3n4) Grade 3 balls roll on Black Oxide races ground to a mirror finish after receiving Magnetite and Cryogenic treatments for hardness and longevity.  ZERØ ceramic bearings feature the roundest balls you can buy without a military license and with virtually undetectable rolling resistance, they are closing in on the magic “zero” resistance wattage number. Double silicone VV seals protect the bearings regardless of weather and are lighter and more flexible than rubber, and are the lowest drag seal available. ZERØ bearings get more email and blog feedback than any other model we make citing a dramatic improvement in rolling speed.
